Document Summary

Controls the parts of the body that work involuntarily. Dendrites- receive information from the synapse (other neurons) Axons- send information from neuron to neuron. Myelin sheath- speeds the transmission of information from one end of the axon to the other. At its resting state it hold -70 microvolts. When the charge reaches the end of the axon it turns into chemicals and those are released in the synapses. Glia cells are white matter in the brain. Are largely responsible for bringing nutrients to the brain and repair what they can. Hits a charge of +40 microvolts = action potential. As soon as the action potential is there, the neuron will fire no matter what. The area in between what we call the presynaptic neuron and the postsynaptic neuron and there we have the synaptic cleft. They work with a lock and key. There is on specific neuron for each specific neurotransmitter. Is believed that where the thinking happens.
